Vehicle wheel rim assembly for motor vehicle

ABSTRACT

A wheel rim assembly is disclosed to include a wheel rim body holding a tire, a plurality of smoothly arched frame bars connected to one another around the periphery of the wheel rim body by plugging a plug at one frame bar into a plughole at another frame bar and hanging a hanger at one frame bar on a locating block at another frame bar, a plurality of packing members respectively fastened to the frame bars to enhance the connection between each two adjacent frame bars, and an annular cushion holding the frame bars and the packing members on the inside around the wheel rim body for supporting the wheel in case the wheel is broken accidentally.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a motor vehicle and more particularly, to a vehicle wheel rim assembly that allows the car driver to drive the car to the car shop safety for receiving a repair work when the tire is broken.

2. Description of the Related Art

When the tire of a vehicle wheel is inflated, high-pressure air supports the tire in shape for running on the road. If a pointed body pierced the tire, the broken tire becomes unable to support the vehicle wheel for normal running on the road, and the broken tire must be repaired immediately. However, It is dangerous if one of the wheels of a vehicle is broken during a high speed running.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a wheel rim assembly for motor vehicle, which supports the tire in shape for enabling the car to run to a repair shop in case the tire is broken during running. To achieve this and other objects of the present invention, the wheel rim assembly comprises a wheel rim body holding a tire, a plurality of smoothly arched frame bars connected to one another around the periphery of the wheel rim body by plugging a plug at one frame bar into a plughole at another frame bar and hanging a hanger at one frame bar on a locating block at another frame bar, a plurality of packing members respectively fastened to the frame bars to enhance the connection between each two adjacent frame bars, and an annular cushion holding the frame bars and the packing members on the inside around the wheel rim body for supporting the wheel in case the wheel is broken accidentally.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1˜9, a wheel rim assembly for motor vehicle in accordance with the present invention is shown comprised of a wheel rim body 2 and a supplementary tire support 1000 fastened to the wheel rim body 2 (see FIGS. 1A, 1B, and 1C).

The supplementary tire support 1000 comprises a plurality of smoothly arched frame bars 10, a plurality of smoothly arched packing members 20, and an annular cushion 30. Each smoothly arched frame bar 10 comprises a frame base 101 covered with elastic material and fitting the periphery of the wheel rim body 2, a first mounting flange 101 a extending along one side of the frame base 101, a second mounting flange 101 b extending along one side of the first mounting flange 101 a remote from the frame base 101, two locating blocks 10 d and 10 e respectively disposed near the two ends of the first mounting flange 101 a, two hangers 10 a respectively pivotally provided at the ends of the first mounting flange 101 a, a plughole 10 c formed in one end of the first mounting flange 101 a, a resilient plug 10 b extended from the other end of the first mounting flange 101 a, and a plurality of fixed screw rods 102 spaced along the first mounting flange 101 a (see FIGS. 4, 5 and 7).

Each packing member 20 comprises a base portion 201 fitting the first mounting flange 101 a of one frame bar 10, a flange 202 extending along one side of the base portion 201, and a plurality of through holes 203 formed in the base portion 21 each for receiving one screw rod 102 of one frame bar 10 (see FIG. 6).

The annular cushion 30 is an internally channeled elastic member adapted to hold the frame bars 10 and the packing members 20 on the inside around the wheel rim body 2 (see FIGS. 8 and 8 a).

Referring to FIGS. 9 and 10 and FIGS. 1˜3 and 6 again, the tire 2000 is fastened to one side of the wheel rim body 2 at first, and then the frame bars 10 are inserted into the inside of the tire 2000 and joined together around the wheel rim body 2 by inserting the plug 10 b of one frame bar 10 into the plughole 10 c of another and fastening the respective hangers 10 a of one frame bar 10 to the respective locating blocks 10 d and 10 e of the adjacent frame bars 10, and then the annular cushion 30 is mounted in the tire 2000 around the joined frame bars 10, and then the packing members 20 are set in the annular cushion 30 to force the through holes 203 of the packing members 20 into engagement with the screw rods 102 of the frame bars 10 respectively, keeping each packing member 20 connected between two frame bars 10.

Referring to FIG. 11, when the tire 2000 is broken, the supplementary tire support 1000 support the broken tire 2000, enabling the driver to drive the car to a vehicle repair shop for repair.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
